The name of the ustad is "Arshad". Yes i know him and my personal experience with him is excellent.
Tell him that you have been referred to him by me (the CG125 whose carb was replaced due to popping sound from exhaust and before that i had head work done as well).
Yes they have all AHL parts and if you want to buy from them for double the price be my guest. Otherwise whole sale rate is of Muhammadi Autos.
Advices
1) Tell Arshad ustad to do all the work himself don't let others do it, that doesn't mean that the rest are not good, it's just that he's a pro
2) While buying from Muhammadi autos they will present you with there types china, AHL and Japani. Only go for AHL in complete AHL packing, i don't trust the other two.
3) Once you tell them about parts and they start bringing them from the back (might take eternity), inspect each parts by taking it out of the packing, if you find any marks or any deformity tell them "no matter how big your shop is i want another piece" just joking just tell them to bring another piece.
4) Get all the big stuff from Muhammadi, and when bike will be opened you can get the small stuff from Anmol as and when required.
Here's a map to help you find them in case you decide to visit them.
